In this second series of Key Matters, presenter Ivan Hewett explores the question of why certain musical keys have become associated with particular moods. For example, why is A major almost always employed by composers to write optimistic, even ecstatic music? And how has E minor become the key of choice for portraying menace and tragedy?

Cellist and composer Philip Sheppard defines the qualities of E minor on Wednesday with music ranging from Brahms, Elgar and Shotakovich to The Clash.
